The first writers of Genesis many centuries ago would not have understood it anyway.
i'm not sure about that.
its easy enough to explain to a child enough nuclear physics where if they wrote the information down, a few thousand years later we would understand it today and recognize that someone knew it, or was shown it.
The chapter in Enoch that explains the water cycle is beautiful to me, its a great example of someone who had a spiritual experience showing them that the water changes forms, mist, ice, liquid, rain, hail, according to rigid rules governed by angels.
Today not many will even read the whole chapter, but its correct that the water cycle operates by rigid rules that God created: its called physics. the whole point of that chapter (or spiritual experience someone had at least 2200 years ago).. is that God is in control of nature and it does not operate on its own authority aka lawlessness.
So when it comes to nuclear decay rates that control how hot the sun is.. no, they don't change. thus the earth really is "ancient" as one of the biblical prophets called it.
If it had just been created 3000 years before him, he would not have called it ancient, as allegedly they believed that adam and others lived almost 1000 years. (if you believe the torah even existed as it does today, in the days of Isaiah)
